More on CAP:
At the Washington Post, Dana Milbank suggests that the Alito nomination may boil down (weirdly enough) to Alito's role in the Concerned Alumni of Princeton:

Thus did Democrats take their last stand against Alito. It had become clear that the committee, with unified GOP support, would clear the judge. Surveying the various lines of attack against Alito -- his opposition to abortion, his support for a powerful president, his conflict-of-interest issues -- Democrats concluded that their best hope was in Alito's membership in a group opposed to gains by women and minorities. Clarence Thomas had Anita Hill. Alito would have the Concerned Alumni of Princeton.

I have been informed by a very reliable source that Senate Judiciary Committee staffers have reviewed the entirety of William Rusher's CAP documents at the Library of Congress and have determined that those documents make no mention at all of Alito.

"Are you now, or have you ever been, a member of the Concerned Alumni of Princeton?" Really, yesterday's exchange between Sen. Schumer and Judge Alito was embarrassing. Senators are never less appealing than when they lay on the sanctimony and feigned shock; "Why oh why," Schumer kept repeating, "did you choose, out of all the groups to which you belonged at the time, to highlight that one in your 1985 letter?" Earth to Schumer: that's what people do when they apply for political jobs in Washington, they try to indicate, in shorthand fashion, where their politics are. The implication Schumer was trying to draw out of this (with his smirks and eye-rolling) was that somehow Alito must have been an active and engaged member of the group, behind the scenes, and that he was covering that up in his testimony and hiding behind his claims not to recall anything about the group, is downright outrageous and not a little revolting.
